Question

If a spoon of copper metal is placed in a solution of ferrous sulphate, ______.

Options

• Cu will precipitate out

• iron will precipitate

• Cu and Fe will precipitate

• no reaction will take place

Answer 1

If a spoon of copper metal is placed in a solution of ferrous sulphate, no reaction will take place.

Explanation:

Copper is less reactive than iron and lies below it in the electrochemical (reactivity) series. Therefore, copper cannot displace iron from ferrous sulphate (FeSO₄) solution. As a result, no redox reaction occurs, and no displacement or precipitation takes place.
